/ Approach Shoes

Hi,
my Approach Shoes are coming to the end and I am thinking of another pair. I have had two pairs of Camp 4`s, and really liked the comfort for moderate walk ins, up to 2 hours and fairly long Descents up to 3 hours, the grip on Grass and non Rock surfaces and the Superb Grip on Rock to such an extent I lead in them on Lower grades sometimes.
No real issues with them and will probably buy another pair, but I am off to Morocco shortly and it could be quite hot there and the routes longish so possibly something lighter weight with less bulk would be good as I will be carrying them up the route, say a Tennie but with Treads. Friends have suggested Innov8 type fell shoes but I do like sticky rubber, can anyone suggest anything.
Cheers
